This was interesting.Lower case Roman Numerals are used to represent minor keys, i.e. the 'vi chord' in the key of C is an A minor chord, usually written as 'Am', not 'A', which would be an A major chord. The 'ii' chord and 'iii' chord are also minors. In all cases the minor chords have a 3rd note that is dropped 1/2 step from their major chords. That is, an A major chord would be the 1-3-5 notes A-C#-E, and an A minor chord would be A-C-E. The seventh chord in this progression is a diminished chord, that means that the 3rd and the 5th notes of the chord, made from this 7th note in this scale, are both dropped 1/2 step. Richard Moore
